Description

Description: TECHNICAL FIELD The present invention relates to an elastic container for transporting and storing bulk materials. The container has an integral lifting loop that faces the extension of the sidewall and forms an opening for the lifting device.

BACKGROUND ART Containers of the type described above have been in use for some time and have been found to be well suited for several purposes. Generally, these vessels have a liner of impermeable material such that when the vessel is filled with a flowable bulk material, the liner is generally first expanded with air. U.S. Pat. No. 4,136,723 shows such a container having bottom edges which intersect one another. The container is preferably provided with two integral lifting loops having an overall width which is approximately equal to half the circumference of the container so that the lifting loop consists of all the longitudinal fibers within the container, GB 1,505,583. By using the device described in the book, the filled container can be placed upright on the floor without the use of special supports. Also, the lift loop can be hung on a hook or the like before being inflated and filled with bulk material. Containers are quickly made for shipping after filling. The container can be made by closing the liner, so that the lifting loop is pressed together to secure the lifting loop in this position to obtain a suitable loop that can be easily placed on a hook or other lifting device. Can be joined. However, the joining of the lift loop to the permanent lift handle can be done before the container is filled with bulk material as described in Norway 830718.

By applying a container with a liner of impermeable material, the liner protects the bulk material in the container and also allows the bulk material in the container to flow out even if the container collapses due to an incorrect operation. Acts to close the container to prevent it. In this connection, it should be explained that the liner must of course remain completely watertight until it is discharged, but experience has shown that the upper part of the liner is damaged by the lifting device into the container. Has been. The liner used to just serve the function of preventing different types of bulk material from escaping the container is not required to protect against fouling.

In some cases, especially during the filling of the powdered bulk material in an elastic container with at least one lifting loop, a filling port is formed which is placed tightly around the filling tube, during the filling operation. The liner mainly acts to prevent the generation of dust.

The liner accounts for most of the total cost of the container. The use of such a liner is therefore not economical if the liner only prevents the outflow of bulk material from the container due to incorrect handling or if the liner is used as a filling port.

However, some bulk goods require protection against dirt and liners are used. When a container with an integral lifting loop is used, regardless of permanent lifting handling, the container that is flowed through the opening of the lifting loop can be provided in the cavity between the liner and the outer container. Holds and stops bulk material against the outer container wall when the container is empty,
The pressure from the bulk material against the liner that fouls the interior of the container can cause the bulk material to exit the container and contaminate the bulk material as it is discharged from the container.

The elastic container shown in U.S. Pat. No. 4,136,723 has a rectangular bottom structure, and when the container is provided with two integral lifting loops having an overall width approximately equal to half the circumference of the container, the container is raised. When closed just below the loop, it is particularly well suited for the transport and storage of bulk material without the use of a liner of impermeable material. A known way of doing this is to tie a rope around the container under a rising loop of, for example, a split ring or the like.

The disadvantage of such a method is that this closing action takes place after the bulk material has been filled into the container so that the rope closes the filling port of the container, and the capacity of the filling device is not fully utilized.

The channels are not necessarily completely closed by this method because the channels can easily be formed when they are pressed together under the raising loop.

The rope knot may disappear.

The performance of the container is underutilized as the net volume is reduced when the container is tied under the filling opening.

The main object of the invention is to achieve a new method of closing a container so that it can operate without the use of a liner of impermeable material and without reducing its transport and storage capacity.

Another object of this invention is to retain the container in the space between the outer container and the liner such that the bulk material is contaminated when the container is discharged and the liner is now pressed against the outer container wall. It is possible to close the container when the liner is used so as to prevent it from being caught.

Another object of the invention is that the liner can be reached by means or a special case of an outer container which is secured against damage by the lifting device.

One way of solving the problems associated with the pressing of contaminants is to protect the complete container with an outer hood of suitable impermeable material. Under the top of such a hood, an opening is made to insert the lifting device into the lifting loop, thus not preventing contaminants from entering the container.

Containers with four lift loops or food lift containers terminate at least 2 above the filling height of bulk material.
Has one container wall. In order to obtain structural stability, a lid of elastic material is fixed at the top of such a container, or where the rising loop is fixed to the container (4-loop elastic ivy) or at the container wall. Is usually fastened. If a lid is used, the lid may be cut with a fill port or the fill port may be affixed to the lid. Further, the filling port can be formed in the extended portion of the fastened container wall. In such a case, a filling port is obtained which can be closed after filling the bulk material in the container.

In such a type of container, the main purpose is accordingly solved by providing an external filling port at the outer end of the container.

It is also known from U.S. Pat. No. 4,010,784 that a four-loop elastic container is provided with a lid secured around the entire circumference of the container top. The lid has a filling port that can be closed by a rope. However, it is difficult to obtain complete closure of the opening by such means.

In a container with an integral lifting loop in which the width of the lifting loop consists of about half of the circumference of the container, the filling port can of course be provided on the outer wall of the container to close the filling port after filling the bulk material. However, the problem is not solved because the lift loop has two openings leading to the void between the container and the liner.

Another means of solving the problem consists in separating the container part having an integral lifting loop from the container cavity filled with bulk material.

It has previously been stated that the container can be closed by filling the container with bulk material and then tightening a rope around under the raising loop. By squeezing the container walls together in this way, partitions are obtained in the "lift section" and the "cargo compartment". Of course, the containers can be roped and squeezed together before being filled with bulk material when the outer filling port is provided in the container wall below where it is squeezed together. The capacity of the filling facility is thus better utilized, but the container rise strength is reduced and the capacity is reduced.

Further development of the idea of partitioning the container in the ascending section and the cargo compartment shows that the problem of separating the ascending section and the cargo compartment can be relatively easily solved by providing a material piece in the ascending section. There is. The arrangement of the material pieces in the container joins the edges of the two openings of the lifting loop to the corresponding edges at both ends. The lift section is then separated from the cargo compartment, the lift section is opened to insert a lifting device, while the cargo compartment is closed to hold bulk material. Containers with integrally overlapping lift loops can be joined to form a separate tube.

However, a fill port leading to the cargo hold is used to hold the bulk material in the container. If the above material piece is T
When it is installed in the opening of the ascending loop by replacing it with a letter tube,
It has been found that the downward leg of the T-tube can be pulled out through one of the two openings of the lifting loop and used as a filling port leading directly into the container cargo compartment.

The length of the T-arm can vary from greater than the width of the flat container to zero as desired.

When the T-arm is equal to zero, the partition material piece can be made by several means.

1) From the circular woven material pieces, 2) Double fold the plain woven material pieces, sew the bottom together and then sew in the same manner as described above, 3) Two plain woven material pieces together During sewing and filling, the filling port is pulled out through the side opening, and after filling, it is bent and returned to the inside of the container. The filling is done from a separate filling port.

A special feature of the present invention is that a pipe-shaped rising section can be formed into a T-shaped or Y-shaped material piece, or inside a container, and can be divided into a rising section and a cargo compartment. It is subject to being formed and closed by providing a piece. Also, the material pieces can be configured to further act as a fill port that can guide bulk material into the cargo compartment. The branch of the material piece used as the filling port can be withdrawn through one of the openings of the raising loop or through the central filling port,
It can be closed after the bulk material has been filled.

Separation of the downwardly extending branch tube from the T-shaped piece of material and its installation as a fill port extending into the cargo compartment is one means of implementing the invention.

This means of locating the fill port in a container with an integral polymerizing ascending loop will be apparent.

The characteristic features of this invention are as defined in the claims.

The present invention will be described in detail below with reference to the accompanying drawings, which show several means for carrying out the invention.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a view showing an elastic tubular piece having several branch pipes, FIG. 2 is a view showing the material piece of FIG. 1 mounted in an elastic container, and FIG. FIG. 4 shows an elastic material piece in the form of a single tube, FIG. 4 shows the upper part of an elastic container on which the elastic material piece according to FIG. 3 is mounted, and FIG. Figure 3 shows the material piece obtained from Figure 3 with both ends completely opened, Figure 6 shows the material section in the form of a T-tube with the top removed from the horizontal part and joined to the top of the elastic container. It is a figure which shows a piece.

BEST MODE FOR CARRYING OUT THE INVENTION FIG. 1 shows a tubular shaped material piece 1 which is attached to an elastic container having an integral raising loop. An elastic material is suitable for the material piece 1 formed in a tubular shape. However, the material piece 1 can be a relatively strong tube and consists of a strong tube with an extension of elastic material. The material piece 1 acts as a means for filling the bulk material to separate a part of the container filled with the bulk material from the rising loop,
A closure means is provided to maintain the bulk material within the container.

The tubular material piece 1 has a T-shape with two horizontal branch pipes b and c having an opening 7 and a vertical branch pipe a which actually forms a filling port. The horizontal branch pipes b and c may be provided with an opening 10 with or without a vertical pipe d shown by a dotted line. In this case, the filling of the bulk material takes place via the pipes a, d. This embodiment can be used if there is a filling opening 8 in the raising loop 9 of the container, as shown by the dotted line in FIG. The branch pipes b, c do not necessarily form a 90 ° angle with the branch pipes a, when the three branch pipes a, b, c can form a Y-shape not shown in the drawing.

The branch pipes a, b, c, d can be of variable length, and the length of at least one branch pipe can be equal to zero. The total length of the branch pipes c and d can be equal to or shorter than the width of the container placed flat. Portions or extensions of the branches a, b, c, d can be used to create a permanent lifting handle 4.

The branch pipe a can be arranged at the center of the horizontal pipe or at an offset from the center. The diameter of the branch pipe a can be smaller than or equal to the diameter of the container.

FIG. 2 shows the upper part of the container 6 with the lifting loop 9 and the opening or arm pit 5 for the insertion of the lifting device.
Attached to the container 6 is a tubular material piece 1 in which an opening 7 is secured to the arm pit 5. The filling port a can be withdrawn before filling through one of the branch pipes b, c, or possibly through the opening 10 or the opening or notch 8 in the separating pipe b, c. The filling can then be carried out through the filling port a. After the filling is completed, the filling port a is closed and the lifting loops 9 are squeezed together and joined in the case shown in FIG. The filling port a may be another filling port a ′ provided on the wall of the container 6. The lifting device can be introduced through the tubular shaped piece 1 and the bulk material in the container 6 is separated from the lifting loop 9. If the container is not topped, the bulk material cannot flow out through the arm pit 5.

The container 6 has two or several lifting loops 9 with more than one permanent lifting handle 4 joined to each other as shown in FIG. 4, the edge of the opening 10 of the piece 1 being the container It is fixed to each edge formed by the notch 8 of 6.

FIG. 3 shows a tubular shaped piece 1 without branch pipes b, c and having a diameter which can be greater than or equal to the flatly placed width 3 between the openings 7. In a manner similar to that shown in FIG. 1, the tube a can have an opening 10 with or without an extension d.

FIG. 4 shows a container 6 having a lifting handle 4 according to FIG. 3 fixed along the edge of an arm pit 5 and a tubular shaped piece 1. Before filling the bulk material, the tube a is pulled out of the outlet 5 as shown in the drawing, and after filling the tube a is glued.

FIG. 5 shows the pieces 1, 1'corresponding to the pieces shown in FIG.
Reference numeral 1'constitutes a tubular filling port with both ends completely open. The opening 7 in FIG. 3 is replaced by a semicircular opening 7 '. When the opening 7'is secured to the lower part of the arm pit 5 and the lifting loops are connected to each other by a sleeved lifting handle in the upper half, the lifting part is separated from the cargo compartment. Since the pipe a is closed after filling, eg by clicking, the rising part is separated from the cargo compartment,
Bulk material cannot flow out of the cargo hold.

FIG. 6 shows a piece 1 ′ with a semicircular cross section which is placed in the elastic container 6. The branch pipes c and d of the piece 1'have an opening 7'fixed to the lower part of the arm pit 5 as shown in the drawing. The edges between the openings 7'are either fastened to the container wall between the arm pits 5 or formed against the container wall by means of a lifting handle sleeve in order to form a rising section tube which can separate the rising part from the cargo compartment. It is squeezed. In order to fill the bulk material into the container 6, an integral part of the piece 1 ', the container 6
Filling port a, which can be another tube a'provided on the wall of the
Need. After filling, the filling ports a, a'are closed,
The bulk material therefore cannot escape from the container 6. 5th, 6th
As shown, the use of piece 1'reduces the consumption of fabric material compared to the use of piece 1 and less fabric material to pull together when the raising loop is connected to the raising handle. Can be done easily.

If a liner is used for the container 6, the liner-filled opening is of course withdrawn through the filling port of the pieces 1, 1 '. The filling of the bulk material is of course carried out in such a way that no bulk material is obtained between the outside of the liner and the pieces 1, 1 '.

The present invention provides a simple means of preventing bulk material from flowing out of a container having an integral lift loop if the container is not topped. Also, a contaminant is obtained that does not damage the liner. The contaminants cannot be located between the container wall and the liner, cannot flow out integrally with the bulk material during discharge, and are contained together. Furthermore,
The members 1,1 'protect the liner against damage by the lifting device. Despite the closure device partition between the ascending section and the cargo hold, a simple filling of bulk material is still obtained.
